Hey wise folks of the M world,
I have an E60 M5 with 62,000 miles, still on the original clutch.
Maybe half a dozen random times the car has failed to engage into gear from second gear (in auto mode) when the car was stopped at the lights.
Its an intermittent issue, but does anyone with experience know if this is the first sign of the clutch going?
Any wisdom greatly appreciated.
Greg

Can't remember what it's called but I'm sure there is a sliding bush which gets "gunk" built up around it and causing gear selecting issues and I think it's a gearbox out job to clean up?

This may be completely wrong though apologies if I'm typing porkies :S, headache at work so memory is even lower than a normal monday morning! M5 board be worth checking as well IMO

If you are in manual mode, can you select 1st or 2nd?

If you are in D what shift speed is selected? If you are less than, IIRC, S3 it will select 2nd.

But really, you should be in manual and S5, much better drive!

Fully agreed! Thought I'd try auto again on the weekend, lasted all of 1 minute, even tried S3 and that lasted about 30 seconds before I went back up!

How? In standard tune the M5 is as safe in the wet as an Audi! Do you drive in M Mode all the time with DSC OFF or something? What tyres are you on?

Believe me it's easy. I was hooning it in MDM 500 mode (no not DSC off too) and hit a small amount of standing water at full throttle and the back end was snaking for a while whilst I managed to correct things. Was a real trouser changing moment and I cannot plant it in the wet anymore!

Whatever tyre you have is irrelevant as in the wet they are hard work especally when driving like an eejit like I was that day. In the RS4 I did the same thing at the same place and it was no problem at all for the AWD system. In a RWD with lots of power it is the same story everytime.

Believe me it's easy. I was hooning it in MDM 500 mode (no not DSC off too) and hit a small amount of standing water at full throttle and the back end was snaking for a while whilst I managed to correct things. Was a real trouser changing moment and I cannot plant it in the wet anymore!

You said it Mr! MDM P500S!! MDM gives you a limited drift (you can hold a drift up to a certain angle of lock) capability so thats why you lost traction. P500S is the harshest of the throttle modes so no wonder you nearly lost it using that. I hate to say it but theres a time and a place. Drive safe in the wet and theres no issue, drive like a scalded sow and you'll end up in the bushes. P400 is absolutely fine in the wet and i had absolutely no bother over the weekend, even with my current DSC and ABS fault. About tyres, the Vreds are astounding in the wet!

yep - i was doing exactly that - tyres weren't the issue, a distinct lack of driving talent was!

as a relatively newcomer to 500bhp super car ownership, i am still experimenting with the cars limits and my own limits (where safe of course), but the situation got the better of me twice last week, so i am easing off for while!

I can relate to that .... Had mine since beginning of September, first RWD car with any claims to power! After 2500 miles I have settled into the car nicely and even occasionally drive in P500S with DSC off, only sometimes though, when I am in the zone mentally! Kind of like when I ride my bike properly I need to be in tune but it is rewarding when you get it right and can be scary when you dont! There's plenty more to get out of it and that will be true for some time to come I dare say.

Due to me coming from many years with a Citroen C4 Grand Picasso I did spend a day with ridedrive including 2 hours in Longcross for high speed & handling instruction and the following day was spent practising in Wales in partly wet conditions so really got to know it better. I can't drive the car in anything other than D5 now with flappy paddles, awesome, just like my G27 wheel for the PC ...

I was referring to your standard tune comment, I didn't know you were meaning in 400 mode only I was thinking no custom rempap for extra power.

500 MDM does not totally disable traction but as you say allows you to hold a drift which is how I like to drive alot of the time in this mode. In the wet at full throttle it's a no no. It will intervene only when the phyiscal limits are reached!

In 400 mode I agree it's no problem at all but now I have got used to it for me it has become sluggish. I feel like there is no torque low down and just prefer to be in MDM with the better throttle response.

The Dry Braking is a cool feature (RS4 B7 had it too).

You can have it in 400 mode and MDM.
They are different settings.

Of course you can but it is a ballache to fiddle with the iDrive and set the M-button to select that when in reality most people want the 500 MDM mode at the press of a button!

I would say I do 90% of my driving in the 500 MDM mode but will in future in the wet stick to the default 400!

I drive 100% of my time in 500MDM mode.... 400 mode only restricts throttle response and stops you getting full throttle, being frank, I get the same result by controlling my use of the throttle.

I once turned traction control off fully and gave it a total bootful in a place I always did with the MDM on... and the difference is massive.... I was very surprised how much MDM actually reigns you in without it being really noticable.

500 mode changes the engine mapping as well as throttle response.

Nope, it doesn't. It only changes the percentages of the throttle opening. Mapping and fueling are identical in all modes.
